wait-for-mouse-buttons-up

Arguments:
nil

Waits until no mouse buttons are down and then returns. It may be
useful to call this function just before calling a function like
get-position or get-box to ensure that a mouse-up from some previous
activity does not also terminate the call to get-position or get-box.
